<span>one of the similarities between monohybrid crosses and dihybrid crosses is : both crosses show the probability of traits the offspring can have.
Not only that, it helps finding out which alleles are resessive and which alleles are on the dominant type</span>
Answer:
The reason why the genotype and phenotype frequences do not match is just because the 1) The genotype based on genes observation,while the phenotype based on physical appearance of the organism externally
Explanation:
the genotype is looking on the arrangement of genes in pair and get its frequency ,while phenotype the external physical appearance of organism is observed to get frequency
Answer:
Because they don't have fertilizer.
Explanation:
Well, if this was a long time ago, then farmers did not have fertilizer. So, there are bacteria on the roots of plants that convert nitrogen into a usable form. It's very important for growing, and when farmers harvest the crop, not much of the nitrogen is returned to the land, so it is not as fertile. Fertilizer is largely consisted of nitrogen, so that is why farmers use fertilizers today. But "a long time ago," farmers did not have fertilizer.
The answer should be B). Helpful traits passed to the next generation through reproduction.
B is correct because in natural selection, if a population cannot adapt over time it will be “naturally selected” and die off, or be near extinction due to non-adaptive ness. Hope this helped!
Answer:
True
Explanation:
Most cells are specialised to perform particular functions, such as red blood cells? that carry oxygen around our bodies in the blood, but they are unable to divide. Stem cells provide new cells for the body as it grows, and replace specialised cells that are damaged or lost.
